Feature Request: Find file by name

[Merovius]

When searching, e.g. for "print_wireless_info.c", there currently are no results. If, on the other hand, I search for "nl80211_xbm_to_percent" I can find the file in the results. It would be great, if the filename would also be indexed, so it is surfaced in search results (and if the search string matches the filename, esp. exactly, it should probably be ranked quite high, I'd argue).
